you really overdid the lip sync and "old video" effect. At some points, only about 20% of the video can be seen. But you also did a really good job at showing the good times that the members of the SOS brigade had together. You should have used a lot more scenes of them and less scenes of lip flaps though. There are so many "together and friendship" scenes in the Endless Eight episodes that you could have completed about 40% of the video with just them.
The idea behind this amv was nice, and I enjoyed watching it. Some lip syncs seemed to be absolutely perfect, but in a lot of cases, they were right after or was followed by a lip sync that was mistimed or awkward. So overall, I give this amv a 3.0 out of 5.
I'm not very good at lip sync, so I can only offer you 2 pieces of advice about it. Lip sync should be somewhat balanced with lyric sync. Your mood sync was perfect though

This guide should be pretty useful to you.

The second advice that I can give you is that you should never lip sync multiple sentences right after each other. Sometimes it is even enough to simply lip sync the end part of the sentence or key words that you want to stand out.
